feat(ipuaro): implement v0.1.0 foundation

- Project setup with tsup, vitest, ESM support
- Domain entities: Session, Project
- Value objects: FileData, FileAST, FileMeta, ChatMessage, ToolCall, ToolResult, UndoEntry
- Service interfaces: IStorage, ILLMClient, ITool, IIndexer, IToolRegistry
- Shared: Config (zod), IpuaroError, utils (hash, tokens), Result type
- CLI with placeholder commands (start, init, index)
- 91 unit tests with 100% coverage
- Fix package scope @puaros -> @samiyev in CLAUDE.md
